PRODUCT OVERVIEW
Flexible Polyurethane Foams Series foams are premium quality water blown flexible foams that can be used for a variety of industrial, special effects and art & crafts and projects. With several to choose from, uses include making theatrical props (swords, knives, hammers, etc.), industrial gaskets, custom padding and cushioning, and more. Flexible Polyurethane Foams are also used as repair materials for seats, cushions and archery targets. Colorants can be added for color effects.
Part A and B liquids are combined, mixed and poured into a mold or other form (apply release agent if necessary). Mixture will rise and cure quickly to a solid, flexible foam. Foams vary by density and offer good physical properties. The lower the number, the more the foam expands. Flexible Polyurethane Foams III is the lowest density foam and expands the most. Flexible Polyurethane Foams 25 is the highest density foam and expands the least. Flexible Polyurethane Foams 15 has a relatively long, 2 minute pot life.
• Flexible Polyurethane Foams IV and Flexible Polyurethane Foams 15 are “Tuff Stuff” foams which are exceptionally strong.
• Flexible Polyurethane Foams 6 and Flexible Polyurethane Foams 8 are “Pillow Soft” foams with a similar softness to pillow or cushion foam.
• Flexible Polyurethane Foams 7 FR is Flame Rated to FMVSS-302 specification • Flexible Polyurethane Foams 23 FR is Flame Rated to UL-94 HB specification

POURING, CURING & PERFORMANCE...
Pouring & Curing - For best results, pour your mixture in a single spot at the lowest point of the containment field and let the mixture seek its level. Allow space in the containment field for the foam to grow as it expands to its ultimate volume. Allow foam to cure for at least 30 minutes before handling. Cure time will be affected by mass and mold configuration.
Mass Concentration / Mold Configuration – Pouring large amounts at a time in certain mold configurations (i.e. cylinder) could cause excess heat to be generated and result in splitting (fissures). Step pouring in layers may resolve this problem.
Improving Surface Finish & Minimizing Voids With Back Pressure - Capping the mold cavity opening with a board that has predrilled holes will improve surface finish for some foams. For more information, watch the video at smooth-on.com/backpressure Is Your Foam Collapsing? - This is a common phenomenon associated with cold temperatures, inadequate mixing or both. Environment or material too cold? Warm it up. Inadequate mixing? You must thoroughly pre-mix both parts A and B. After combining A and B, mix thoroughly. If using a mechanical mixer, mix for 30 seconds. When hand mixing, mix quickly and aggressively, almost whipping the material.
